St170 to rwd sierra
Hi , I'm planning on putting an st170 engine into my sierra . The only thing I think I'm going to struggle with is wiring. I'm hoping to run it on the original injection for the time being as I dont have a very big budget at the minute. eventually I want to run throttle bodies or maybe even turbo . Anyway what I'm asking is does anyone have a wiring diagram of a cut down loom to get rid of all the rubbish you don't need . Any help appreciated thanks

Hi Tom,
Cool project. What ecu does the st170 use EEC-IV or EEC-V, I'm guessing EEC-V? But if its EEC-IV I should be able to help you with a wiring diagram.
The EEV-IV has a light grey connector with 60pins (20 on each row), the EEC-V has a dark grey connector with over 100 pins.

Sorry Tom thats a little out of my experience zone, I tend to work more with the EEC-IV and stand alone systems. There should be some usable diagrams on autodata and online however I think you might struggle with the Ford PATS system.

I've found that life I needed.. It's HERE!!
Pats is the easy bit. You cant bypass it but you can use it.
Before you get started you will need the inlet mani' as the ecu will not like the lack of imrc.
It wont fit a sierra. you will have to get a little creative with that.

The key to using the ecu is the Pat's immobilizer. You must get at least one key with chip that is matched to the ecu.

The Immobilizer.
The picture below shows the transceiver or aerial. This is found behind the steering cowl. The ring sit’s around the ignition switch and is held to the steering column with one screw.
This is the wiring plug.
It needs cutting from the car with as much wire as can be pulled free.
Retaining clip shown at the bottom.
There are four pins, They may be colour coded as above or they may be all black as shown in the photo. This depends on the age of the donor.
that should get you started. The rest can be found here .
